  • Chemistry C2.
    • Subtances.
      • Immiscible.
        • substances that will not mix together but will form distinct layers.
  • ie) water and oil, water is separated from oil using a funnel.As soon as all the water runs out of the funnel, tap closed
    • Immiscible.
      • substances that will not mix together but will form distinct layers.
  • Miscible.
    • Subtances.
      • Liquids are mixed and stay together
    • Liquids are mixed and stay together
    • separated using distillation or fractional distillation.
      • Rates of Reaction.
        • Chemistry C2.
          • Larger surface area-more particles exposed and available for collision.
            • high conc- particles are closer together,more collisons
        • Endo+Exo.
          • Exo- rise in temp, heat is transferred to surroundings-combustion. Energy released when bonds are made.
            • Endo+Exo.
            • Endo-fall in temp,heat transferred in FROM surroundings-ie-dissolving ammonium nitrate crystals in water. Energy must be supplied to make bonds.
